TYPE-WRITER ATTACHMENT.

Specification of Letters Patent.

Patented July 25, 1911.

Application filed July 8, 1909. Serial No. 507,251.

- whereby, in a glven instance, the typewriter may be to a degree vibratorily insulated from the supporting structure, lessenin the noise accompanying the operation 0 the typewriter, and whereby from the operation itself may be eliminated a considerable portion of the jar and shock incident to the play and limitations of lay of the keys. The attachment, organized according to the invention, will thus serve to a definite degree as a shock absorber, rendering. the use of the typewriter less unpleasant to and less a strain upon the nerves and muscles of the operator, and decreases greatly the irrit-ation to the nerves of other persons within hearing distance of its point of operation.

In addition to the above objects, .theinvention is directed at the provision of a typewriter attachment of the general nature set forth which will be relatively simple and inexpensive in construction, durable, positive and responsive in operation, and generally superlor in point of eficiency and serviceability.

With the above and other objects in view,,

the invention consists in the novel provision construction, combination, association and relative arrangement of parts, members and features,'all as hereinafter described, shown in the drawing, and finally pointed out in claims.

In the drawing :Figure 1 is aside elevation, partly in section and partly broken away for clearness of illustration, of a portion of a typewriter frame and certain typewriter features, together with typewriter attachments embodying the invention, said figure illustrating the method of application and use of the im roved attachment constituting the inventlon in assemblage with a ty ewriter; Fig. 2 is an enlarged detail vertical sectional view of one of the attachments shown in Fig. 1; and, Fig. 3 is a transverse sectional view, taken upon the slight movement. 0 The jar and noise normally accompanying line 33, Fig. 2, and looking in the direction of the appended arrows.

Corresponding parts in all the figures are denoted by the same reference characters.

Referrin with particularity to the drawing, A deslgnates the attachment embodyillustrated in Fig. 1 as operatively applied to a t pewriter B, and in connection with one o the side frame members 6 thereof. The attachments A, which serve as feet for the typewriter, are disposed beneath the latter and between the same and a supporting structure C, which may or other obgect. The attachments or feet con sist of an u per surface of a desk, table mg the invention, two of the same being A are preferably provided in such plurality and at such points, as to support the typewriter in entirety. Each of the attachments or feet A comprises two relatively moveable members, 0 and al respectively, and tenslon means e and operative connections 7 between the members 0 and d. One of the members 0 of eachattachment is formed-to rest upon the supporting structure (3; and

the other of the members (Z is ada ted and formed to bear against orwith re ation to the typewriter or a frame member 3 thereof. The impact of the blows of the keys and type bars upon the other parts of the typewriter causes relative movement of the members c and d, which relative movement is o posed by the tension means. 6, and it t erefrom results that the typewrlter rises and falls in artial compensation for the stress of the b ows accompanying the manipulation of the keys, so that the normal abrupt terminations of the playoff each key and its attendant arts is converted into the entire typewriter.

the operation of the keys and attendant parts, with respect to the nerves and muscles of the o erator, are thus modified if not entirely eliminated. Furthermore, as the impact of the moving parts of the typewriter is transmitted to the supporting structure U through the resilient tension means 6, the force of such impact is largely taken up by the tension means, and the sup orting structure is but sli htly vibrate in common with the typewriter. The noise and clatter usually accom anying the o eration of the typewriter is t us substantia ly modified.

One particular constructionand arrangement 0 parts and features of a typewriter similarly proportioned opening formed centrally of the disk 5, the post and said opening being preferably cylindrical in form. The disk 4 is provided upon the facial portion opposed to the disk 5 with a circular flange 7 having aperipheral groove 8; and

upon the disk 5 is formed'or located a simi-- lar. circular flange 9 having a corresponding peripheral groove 10. A coil spring 11 is disposed between the disks 4 and 5', the end portions of the same being seated in and received by the grooves 8 and 10,. as, clearly shownin Fig. 2, said spring 11 constituting the tension means e. Thecoil spring 11 loosely surrounds and incloses the stem or post 6 which is' free to play within the same.

The disk 4 is provided witha pad or cap 12 which covers the surface of the same which 'is exposed to wear; said pad or cap being provided with an edge flange 13 which sur- 1 .rounds the peripheryof'the disk 4. The pad or oap and its flange are preferably composed of rubber or rubber composition, and, the elasticity thereof causes the flange 13 'to bind upon the disk 4 and hold the'pad or cap in-placer The disk 5 is preferably provided with a pad or cap. 14 fitting the wearing surface thereof and having an edge flange 15 which taken in connection with the accompanying surrounds the periphery of the disk 5,-the

pad 14 and its flange 15 being preferably of rubber or rubber composition so that the elasticity of the same causes the flange to bind upon the disk and hold the pad or cap in place. The pad or cap 14 is provide with a centrally located tubular nipple 16 which risesffrom the face thereof opposite to that which is in contact with the d1sk5;

the pad or cap 14 being provided with a central opening in registration with the tubular passage, 17 in said nipple; said passage v17 and the said registering opening in the cap 14 both registering with a centrai opening through the disk 5, and all accommodating the stem or post 6 and being of substantially the same form and dimensions so that the stem 6 can play within the tubular passage 17.

Disks 4 and 5 and theirflanges 7 and 9 are preferably of integral metallic formation, in each pair, and the stem or post 6 is preferably metallic in nature and may be attached to the disk 4 and its fiange 7 or formed integrally therewith.

The operation, method of use and ad-- vanta es .of the improved attachment con-- stitutlng the invention will be readily understood from the foregoing description,

Each of the attachments or feet A, organized as set forth and illustrated, and with the parts and features thereof assembled as shown in the drawing, is connected with the typewriter or a frame member 1) thereof, by inserting the tubular nipple 16 of the cap 14 drawing and the following statementwithin a frame opening 18 which the nipple 16 is formed to fit. The frame then rests directly upon the disk 5, being the upper of the two disks, or upon the pad or cap- 14 which covers the'upper surface of the same. The disk 4, or its pad or cap 12 is then placed. upon the desk or other supporting structure'C. The weight of the typewriter or that portion of the same which is imposed upon the respective pad or cap 14, is transmitted to the supporting structure C through the two pads or caps 12 and 14, the two disks 4 and '5 and the interposed coil spring 11. The stem or post 6 acts as-a centering means to keep the other parts in proper members 0 and 03 may have proper relative play as determined by the elasticity of the tension means 6, saidstem or post 6 playing freely within and through the openings in the disk 5 and the pad or cap 14 together and in connection with the-supporting structure and the typewriter.

It will be understood that the action of each of the attachments A throughout the plurality of the same employed in any given instance is the same as that above described; each attachment serving in the common function of resiliently and yieldingly supporting its superimposed ,portion of the typewriter with the advantages and objects fully hereinbefore recited.

1 do not desire to be understood as limiting myself to the specific provision, construction and arrangement of parts, members and features shown and described as embodying the invention; but reserve the right to vary the same, in adapting the invention to varying conditions of use, without departing from the spirit of the invention and the terms of the following claims.
